我正在尝试创建我的第一个应用程序，该应用程序允许我跟踪我的耐力赛（越野车）训练进度，无论是在比赛模式还是训练模式中，碰巧我的应用程序必须具备的基本功能之一是地图上的跟踪系统，以便保存我的路线。我正在尝试在我的应用程序中实现地图，但我发现了几个错误，如果格式或我在此处写的任何内容不正确，我想道歉，这是我第一次在这里提问。我使用的是 Xcode 15.4 和 iOS 17.5，非常感谢您抽出时间。

struct SecondView_Previews: PreviewProvider {
    static var previews: some View {
        SecondView()

我按照某人的建议进行了更改：不要使用 ForEach，而使用带有 Map 的 commentItems，但这也不起作用。
